The old boxer Song Wuyang was suddenly attacked by the disciples of the Baiwu Pavilion. Fortunately, his daughter Song Yingying and his disciple Zhao Zhihao were rescued in time. Song Wuyang knew that he was old and weak, and he no longer had enough energy to teach martial arts to Zhao Zhihao. At the same time, he was worried that the evil faction would take away the championship of the national competition, so he instructed Zhao Zhihao in person to change to the Shangwu Pavilion to learn skills, hoping to win the championship.On the way to become an apprentice, Zhao Zhihao encountered a criminal attack on the singing girl, and drew his sword to help rescue Miss Yan. After being rescued, Miss Yan wanted to promise her, but Zhao Zhihao already had a junior sister Song Yingying in his heart, so he refused Miss Yan's love.Later, Zhao Zhihao was repeatedly disturbed by the disciples of the Baiwu Hall, and was even injured by the foreign aid of the Baiwu Hall, the Japanese Randren.
